Abstract
A power transmission device for connecting a rotation shaft with a mechanism for converting rotational movement into reciprocal movement. The rotation shaft is concentrically accommodated in a rotation shaft sleeve having an outer wall with a circumferential groove. A connecting sleeve, with a plurality of circumferentially arranged through-holes with a ball mounted in each through-hole, slidably receives the rotation shaft sleeve. A sliding sleeve having a circularly formed internal recess is mounted over the connecting sleeve and is slidable to position the balls in the through-holes such as to either connect or disconnect the connecting sleeve from the rotation shaft sleeve.
